8．Plants are flowering faster than scientists predicted（预测）in reaction to climate change，which could have long damaging effects on food chains and ecosystems．
Global warming is having a great effect on hundreds of plant and animal species around the world，changing some living patterns，scientists say．
Increased carbon dioxide（CO2）in the air from burning coal and oil can have an effect on how plants produce oxygen，while higher temperatures and changeable rainfall patterns can change their patterns of growth．
"Predicting species'reaction to climate change is a major challenge in ecology，"said the researches of several U．S．universities．They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services．
The study，published on the Nature website，uses the findings from plant life cycle studies and experiments across four continents and 1，634species．It found that some experiments had underestimated（低估）the speed of flowering by 8.5times and leafing by 4times．
"Across all species，the experiments under-predicted the speed of the advance-for both leafing and flowering-that results from temperature increases，"the study said．
The design of future experiments may need to be improved to better predict how plants will react to climate change，it said．
Plants are necessary for life on the Earth．They are the base of the food chain，using photosynthesis（光合作用）to produce sugar from carbon dioxide and water．They let out oxygen which is needed by nearly every organism on the planet．
Scientists believe the world's average temperature has risen by about 0.8℃since 1900，and nearly 0.2℃every ten years since 1979．
So far，efforts to cut emissions（排放）of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃this century-a point scientists say will bring the danger of a changeable climate in which weather extremes are common，leading to drought，floods，crop failures and rising sea levels．

57．What is the key information the author wants to give in Paragraph 1？B．
A．Plants'reaction to weather could have damaging effects on ecosystem．
B．The increasing speed of flowering is beyond scientists'expectation．
C．Climate change leads to the change of food production patterns．
D．Food chains have been seriously damaged because of weather．
58．We can learn from the study published on the Nature website thatC．
A．plants'flowering is 8.5times faster than leafing
B．there are 1，634plant species on the four continents
C．scientists should improve the design of the experiments
D．the experiments failed to predict how plants react to climate change
59．Scientists pay special attention to the study of plants becauseB．
A．they can prove the climate change clearly
B．they are very important in the food chains
C．they play a leading role in reducing global warming
D．they are growing and flowering much faster than before
60．What can be inferred from the last two paragraphs about the world's temperature？D．
A．It has risen nearly 0.2℃since 1979．
B．Its change will lead to weather extremes．
C．It is 0.8℃higher in 1979than that of 1990．
D．It needs to be controlled within 2℃in this century．

7．In 1991，high in the mountains of Europe，hikers made a discovery：a dead man partly frozen in the ice．However，the police investigation soon became a scientific one．Carbon dating indicated that the man died over 5，300years ago．Today he is known as the Iceman and has been nicknamed"?tzi"for the ?tztal Alps where he was found．Kept in perfect condition by the ice，he is the oldest complete human body on the earth．
Scientists think he was an important person in his society．An examination of his teeth and skull tells us that he was not a young man．His arms were not the arms of a laborer．His dagger（匕首） was made of stone，but he carried a copper axe．This implies wealth，and he was probably from the upper classes．We know he could make fire，as a fire-starting kit was discovered with him．Even the food he had eaten enabled scientists to reason exactly where in Italy he lived．
But why did the Iceman die in such a high and icy place？There have been many theories．Some said he was a lost shepherd．Others thought he was killed in a religious ceremony．Over the years since he was found，tiny scientific discoveries have led to great changes in our understanding of the story of the Iceman．The newest scientific information indicates that he was cruelly murdered．"Even five years ago，the story was that he fled up there and walked around in the snow and probably died of exposure，"said Klaus Oeggl，a scientist at the University of Innsbruck in Austria．"Now it's all changed．It's more like a…crime scene．"
In June 2001，an X-ray examination of the body showed a small dark shape beneath the Iceman's left shoulder．It was the stone head of an arrow．It had caused a deadly injury that probably killed him very quickly．In 2003，an Australian scientist discovered the blood of four different people on the clothes of the Iceman．Did a bloody fight take place before his murder？Injuries on his hand and head indicate that this may be true．One theory，put forward by archeologist （考古学家） WalterLeitner，says that the Iceman's murder was the end of a fight for power among his people．However，this idea is certainly debatable．

66．What does"?tzi"refer toA．
A．the oldest perfectly preserved human body
B．the most famous tourist attraction?tztal Alps
C．an important discovery by the police of Europe
D．the person living in ?tztal Alps for a long time

B．he made a fire-starting kit
C．he had a higher social status
D．he was born at a village in Italy
68．According to Klaus Oeggl，the Iceman died fromD．
A．a serious diseaseB．a snow disaster
C．a religious faithD．a terrible murder
69．What is the passage mainly talking aboutC？
A．The life of ancient people in the AlpsMountains．
B．The cruel religious life of the Europeans in the past．
C．The discovery andpossiblecause of death of the Iceman．
D．The application of carbon dating technology to the Iceman．
